Hi All, I'm looking for information on ultra-thin silicon membranes (thickness less than 500nm). In particular I'm looking for 1) papers which describes realization of such membranes, up to now I've found only Journal of the Korean Physical Society, Vol. 53, No. 2, pp. 579-583 J. Vac. Sci. Technol. B 28(1) 2) applications of ultra-thin silicon membranes Is there any suggestion on this topic ? Thanks in advance, Andrea Mazzolari
